Subterfuge

 is a support skill in Tyranny.

Description
The Subterfuge skill determines a character's ability to move through their environment, to detect and manipulate hidden traps and devices, and to open locked chests and doors. It is also used in dialogue to determine your ability to deceive or trick the person you're speaking with.

Compared to other support skills, Subterfuge checks give more experience points than Lore checks, but less than Athletics checks. In New Game+, it may be necessary to shift points from other skills to boost Subterfuge (or train the skill with a trainer) as the experience gained from using it may not be enough for the skill to catch up with increased requirements due to increase in character levels.
